. vTo all 'whom t ma'g/ concern Be it known that I, JOSEF Anna, a citizen of the United States, and a resident of New York city, in the county and State of New .York, have invented certain new and useful Improvements' in I-Iydi'omobiles, of which the following is a specification. 0

This invention relates to a hydromobile of novel construction, which is well adapted for sporting purposes and may be folded up into a small compass when placed out-of commission.

The invention consists in the various features of novelty more fully pointed out 1n the specification and appended claims.

In the accompanying drawing:

Figure 1 is a plan partly in section, of a hydroinobile embodying my invention;

Fig. 2, a longitudinal section on line 2-2 Fi 1' Fig.3, a section through one of the floats, showing it collapsed;

Fig. 4, a cross section on line Fig. 1;

Fig. 5, a longitudinal section on line 5 5 Fig. 2, and

Fig'. 6, a detail of the rack and pinion transmission. Y

The hydromobile is constructed on the catamaran principle, being composed of two floats that carry a cross deck or platform. Each float is formed in three cylindrical sections, of which the central section l, is adapted to telescope the stern section 2, which in turn is adapted to telescope the bow section 3. The central section ,1, is split longitudinally along its inner side so thatit may yield somewhat during the telescoping operation, and is here provided with a pair of spaced laterally extending flanges 4 the upper one of which-supports the platform 5. This platform is slotted along its edges and is here engaged by bolts 6 that pass likewise through apertures of flanges 4, and through a packing strip 7 interposed between said flanges. By removing nuts 8v carried by the bolts, the platform may be disconnected from the float-sections, so that in this way, the device may be readily dismembered.

The rear float sections 2 are open at the front and back, and may be closed watertight at the back by hinged lids 9, while a packing ring 10 is interposed between the overlapping ends of sections 1 and 2. The

front float section'3, has a pointed or coni form bow, while a similar packing ring 11 is interposed between the overlapping sections 1 and 3, the thickness of ring 11 being however, somewhat greater than that of ring 10 in order to compensate for the di'erence in diameters between the sections 3 and 2.

From platform 5, depends a housing 12,

` containing the bearings for the shaft 13 of the propeller screw 14. The latter is operated in the following manner: A hand lever 15 is adapted to be inserted into the socketed end of a two arm lever 16 turning on fulcrum 17. To opposite ends of lever 16 are pivoted by links 18, a pair of racks19, en-

- gaging pinions 20 loose on an upright shaft 21. In proximity to each pinion there is fast on shaft 21, a ratchet wheel 22 engaged 1 by a pawl 23 pivoted to the pinion, the teeth of the two ratchet wheels being opposed to each other,

Shaft 21 is by bevel wheels 24 intergeared with propeller shaft 13, so that by moving hand lever 15 alternately forward and backward, the ratchet wheels will impart continuous rotary movement to shaft 21 and .consequently to propeller 14, the pawl f the inert wheel 22 gliding freely over the teeth y zontal rod 32, the latter vbeing received within a suitable guide 33 of the platform to which it may be held by a clamp screw 34. Thus the saddle may beremoved from the platform and then its support may be fold-l ed so as to occupy a minimum amount of space.

' The correlation of the parts is such that when the platform is disconnected from the floats and the sections of the latter are telescoped, the platform together with all its appurtenances may be readily slipped into one of the floats through lid 9, the drawing showing the width of the platform somewhat exaggerated for the sake' of displaying the propelling mechanism on a larger scale.

It will be seen that. the hydromobile constructed as described is well adapted for use especially on beaches, rivers, or lakes, that it may be readily operated, and that it can be folded up to occupy a minimum amount of space during portage or storage.

I claim:

1. A hydromobile comprising a pair of floats, each composed of a longitudinally split and flanged section, a stern section and a bow section adapted to be telescoped by the flanged section, and a platform adapted to removably engage the flanged section.

2. A hydromobile comprising a pair of floats, each composed of a central longitudinally split section, a stern section and a bow section adapted to be telescoped by the central sectiona packing interposed between the central section and the stern section, a further packing interposed between the central section and the bow section, and a plat. form adapted tov be removably connected to the central section.

3. In a hydromobile, a two arm lever, a pair of racks pivoted thereto, a pair of pinions engaged by the racks, a pair of oppositely disposed ratchet wheels, pawls on the pinions that engage said ratchet Wheels, a shaft on which the ratchet wheels are mounted, and a propeller shaft intergeared with the first named shaft.

4. A hydromobile `comprising a pair. of

telescopic floats, a platform removably seA cured thereto, a saddle, a foldable support for said saddle, and means for removably securing said support to said platform.

5. A hydromobile comprising a pair of telescopic floats, a platform removably secured thereto, a foldable 'saddle and hydro mobile propelling means carried by the platform, said platform, saddle and propelling means being adapted'to be received Within one of the floats.

6. A hydromobile comprising a pair of tubular floats, each composed of a plurality Y of telescoping sections, packings between said sections, a. Water tight lid on the rearmost section, and a removable platform carried by the floats and adapted to be projected into either one of said floats.
